python - 如何为 CloudError : Azure Error: RequestsLimitReached 添加客户端限制

Question

创建 Azure 托管磁盘快照时出错。下面是异常堆栈和Azure云返回的消息

Exception call stack:
"Traceback (most recent call last):"
File ""azure/azure.py"", line 188, in createsnapshot"
    disksnapshot = dsksnapshotcreation.result()"
File ""/tmp/myapp/libs/azure/lib/msrest/polling/poller.py"", line 183, in result"
    elf.wait(timeout)"
File ""/tmp/myapp/libs/azure/lib/msrest/polling/poller.py"", line 201, in wait"
    raise self._exception  # type: ignore"
File ""/tmp/myapp/libs/azure/lib/msrest/polling/poller.py"", line 152, in _start"
    self._polling_method.run()"
File ""/tmp/myapp/libs/azure/lib/msrestazure/polling/arm_polling.py"", line 400, in run"
    raise CloudError(self._response)"
"msrestazure.azure_exceptions.CloudError: Azure Error: RequestsLimitReached"

消息:从可写资源(托管磁盘)复制的尝试过多；请使用快照源在短时间内创建多个副本。

看起来我需要添加某种客户端限制。但Azure python SDK并没有返回文档https://learn.microsoft.com/en-us/azure/azure-resource-manager/management/request-limits-and-throttling中提到的节流信息.

如何使用Python SDK获取“retry-after”等信息？

Answer 1

您在调用 create_or_update() 时是否使用了 raw=True ？这样，SDK 轮询器就可以返回服务端返回的 http header 。
